[0002] Handheld cleaning devices, such as handheld vacuum cleaners, are common household cleaning equipment, characterized by their small size and light weight, making them suitable for cleaning homes. CN202410199974.0 discloses a handheld vacuum cleaner main unit, including a base, a dust cup, a motor, and a battery pack. The base has a longitudinally extending air duct, with an inlet at the front for drawing in dust and an outlet at the rear. The dust cup is located on the top of the base, with its air inlet connected to the air outlet. The motor is also located on the top of the base and coaxially aligned with the base in the front-to-back direction, connected to the dust cup's outlet. The battery pack is located at the bottom of the base and electrically connected to the motor. During operation, the motor generates negative pressure powered by the battery pack, causing the air duct to draw dust into the dust cup for separation. The separated air is then discharged through the motor.

[0003] However, with the above structure, the dust cup is small in size in the front-to-back direction due to the limitations of the motor installation position and the overall structural size. The dust cup capacity is small and it is prone to clogging during dust collection. This requires users to clean the dust cup and its internal filter structure frequently, which greatly affects the user experience.

[0004] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0039] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0040] Please see Figure 1 and Figure 2As shown, a handheld cleaning device corresponding to a preferred embodiment of the present invention includes: a base 100, including a mounting member 110 and a handle member 120 extending downward from the bottom of the mounting member 110, with an air duct formed within the base 100; a dust cup 200 disposed on the top of the mounting member 110, communicating with the air duct and used for air-dust separation; a suction motor 400 disposed on the bottom of the mounting member 110, communicating with the air duct and used to generate airflow along the air duct; and a battery pack 300 disposed on the bottom of the handle member 120 and electrically connected to the suction motor 400; wherein the projections of the suction motor 400 and the dust cup 200 in the height direction of the handheld cleaning device at least partially overlap, and the projections of the suction motor 400 and the handle member 120 in the length direction of the handheld cleaning device at least partially overlap.

[0041] This invention, by placing the dust cup 200 at the top of the mounting component 110 and the suction motor 400 at the bottom of the mounting component 110, avoids the limitation of the dust cup 200 by the suction motor 400 compared to a coaxial arrangement of the two. Without increasing cost or structural size, the dust cup 200 can be made larger in the length direction of the handheld cleaning device, increasing its capacity and making it less prone to clogging. This solves the problem of frequent cleaning of the dust cup 200 and replacement or cleaning of its filter structure, improving the user experience. The suction motor 400 and the dust... The projections of the dust cup 200 in the height direction of the handheld cleaning device at least partially overlap, and the projections of the suction motor 400 and the handle 120 in the length direction of the handheld cleaning device at least partially overlap. The suction motor 400 is compactly installed, greatly reducing the size of the device and improving convenience. The dust cup 200 and the suction motor 400 are respectively located at the top and bottom of the mounting part 110, and the battery pack 300 is located at the bottom of the handle 120. The new arrangement of the dust cup 200, the suction motor 400 and the battery pack 300 can distribute the weight of the cleaning device, thereby reasonably distributing the overall weight of the machine and improving the user's comfort.

[0042] Furthermore, the air duct includes a first air duct 130 and a second air duct 140. The first air duct 130 includes a first air duct inlet 131 and a first air duct outlet 132. The first air duct inlet 131 is used to draw in dusty air, and the first air duct outlet 132 is connected to the air inlet 210 of the dust cup 200. The second air duct 140 includes a second air duct inlet 141 and a second air duct outlet 142. The second air duct inlet 141 is connected to the air outlet of the dust cup 200, and the second air duct outlet 142 is connected to the suction inlet 420 of the suction motor 400. During operation, the suction motor 400 applies negative pressure to the air duct, causing the dusty air to flow sequentially through the first air duct inlet 131, the first air duct 130, and the first air duct outlet 132 into the dust cup 200. The dust is retained in the dust cup 200, and the filtered airflow flows sequentially through the second air duct inlet 141, the second air duct 140, and the second air duct outlet 142 to the suction motor 400.

[0043] Furthermore, the mounting component 110 and the handle component 120 can be integrally formed or separately formed and then assembled together; this utility model does not limit this. The mounting component 110 is an elongated strip structure extending along the length of the device, having a front end and a rear end. The handle component 120 is connected to the rear end of the mounting component 110. A receiving space is formed between the bottom of the mounting component 110 and the side of the handle component 120 facing the front end of the mounting component 110, and the suction motor 400 is located in the receiving space. By arranging the suction motor 400 in this receiving space, the space of the base 100 can be rationally utilized, making the whole machine more compact, avoiding an increase in the structural size of the device, and meeting the requirements of handheld design.

[0044] Furthermore, the first air duct 130 is formed inside the mounting member 110 and extends along the length of the equipment. The first air duct inlet 131 is located at the front end of the mounting member 110, and the first air duct outlet 132 is located near the rear end of the mounting member 110. The dust cup 200 is parallel to the length direction along its axis, and its two ends extend to both ends of the mounting member 110, thereby effectively increasing the size of the dust cup 200 in the length direction of the equipment.

[0045] Furthermore, a second air duct 140 is formed inside the handle 120; or the handle 120 and the battery pack 300 cooperate to form a second air duct 140, so that even after the suction motor 400 is positioned below the dust cup 200, it can still act on the dust cup 200.

[0046] Specifically, the handle 120 includes a grip portion 121 and a connecting portion 122. The grip portion 121 has a strip-shaped structure, with an upper end and a lower end. The upper end of the grip portion 121 is connected to the mounting member 110, and the connecting portion 122 is connected to the lower end of the grip portion 121. The battery pack 300 is connected to the connecting portion 122. The second air duct 140 includes a first section 143 with a second air duct inlet 141 and a second section 144 with a second air duct outlet 142. The first section 143 and the second section 144 are connected. The first section 143 is formed inside the grip portion 121, and the second section 144 is formed inside the connecting portion 122, or the connecting portion 122 and the battery pack 300 cooperate to form the second section 144. Preferably, in this embodiment, the connecting portion 122 and the battery pack 300 cooperate to form the second section 144, so as to reduce the size of the connecting portion 122 in the height direction of the device, and the airflow flowing through the second section 144 can also achieve effective heat dissipation of the battery pack 300.

[0047] The first segment 143 extends along the length of the gripping part 121. The second air duct inlet 141 is located at the upper end of the gripping part 121. The lower end of the gripping part 121 has a first opening. The connecting part 122 has a second opening at the position corresponding to the first opening. The first opening and the second opening cooperate to form a receiving part that connects the first segment 143 and the second segment 144. The second segment 144 extends along the length of the equipment. The second air duct outlet 142 is located at the end of the second segment 144 near the front end of the mounting member 110.

[0048] Preferably, the handle 120 further includes a reinforcing portion 123, which is located on the side of the grip portion 121 facing the front end of the mounting member 110. The reinforcing portion 123 has a strip-shaped structure, also having an upper end and a lower end. Its upper end connects to the mounting member 110, and a connecting portion 122 connects the lower ends of the grip portion 121 and the reinforcing portion 123, resulting in higher structural strength after the connecting portion 122 is connected. There is a certain gap between the reinforcing portion 123 and the grip portion 121 to avoid obstructing the hand holding the grip portion 121. The mounting space is formed between the bottom of the mounting member 110 and the side of the reinforcing portion 123 facing the front end of the mounting member 110. The grip portion 121, the connecting portion 122, and the reinforcing portion 123 can be integrally formed or separately formed and then assembled together; this utility model is not limited thereto.

[0049] Furthermore, the dust cup 200 has a conventional structure and can be snapped together with the mounting piece 110 for quick assembly and disassembly. Both the air inlet 210 and the air outlet are located on the periphery of the dust cup 200. After the dust cup 200 is installed and positioned on the mounting piece 110, the air inlet 210 is sealed and connected to the first air duct outlet 132, and the air outlet is sealed and connected to the second air duct inlet 141.

[0050] Furthermore, the battery pack 300 includes a battery pack shell 310 and a battery cell body (not shown) disposed within the battery pack shell 310. The bottom of the connecting portion 122 and the top of the battery pack shell 310 are joined to form a second segment 144. For example, the bottom of the connecting portion 122 may be recessed inward to form an air duct groove, and the top of the battery pack shell 310 may be adapted to cover the air duct groove to form the second segment 144; or the top of the battery pack shell 310 may be recessed inward to form an air duct groove, and the bottom of the connecting portion 122 may be covered to form the second segment 144.

[0051] In one embodiment, the battery pack shell 310 is detachably disposed at the bottom of the connecting portion 122, and the battery pack shell 310 can be snapped together with the connecting portion 122, making the battery pack 300 modularly designed and convenient for subsequent disassembly and replacement. Admittedly, in other embodiments, the battery pack shell 310 and the connecting portion 122 can also be non-detachably connected, making the second segment 144 formed by the two together more reliable and avoiding a reduction in the sealing performance of the second segment 144 due to frequent disassembly and assembly.

[0052] Furthermore, the axial direction of the suction motor 400 is parallel to the height direction of the device. The suction motor 400 includes a motor housing 410 and a motor body (not shown) mounted on the motor housing 410. The motor housing 410 is located between the bottom of the mounting member 110 and the top of the connecting part 122, with the bottom of the motor housing 410 connected to the top of the connecting part 122. The second air duct outlet 142 is located at the top of the connecting part 122, the suction inlet 420 is located at the bottom of the motor housing 410, and a suction outlet 430 is formed on the periphery of the motor housing 410, located in the area near the top of the motor housing 410. The suction outlet 430 is used to directly communicate with the external environment and to discharge the airflow processed by the suction motor 400 to the outside of the handheld cleaning device. Specifically, after the dust cup 200 separates the air and dust, the clean air enters the suction inlet 420 of the suction motor 400 through the second air duct inlet 141, the second air duct 140, and the second air duct outlet 142 in sequence. After flowing through the motor body, it is finally discharged from the suction outlet 430 on the side of the motor housing 410, completing the entire airflow circulation process.

[0053] Preferably, the top of the motor housing 410 is connected to the bottom of the mounting part 110, and the side of the motor housing 410 is connected to the reinforcing part 123. That is, the motor housing 410 is simultaneously connected to the mounting part 110, the reinforcing part 123, and the connecting part 122, which effectively improves the connection strength of the motor housing 410 and enhances the reliability of the suction motor 400 during operation. The motor housing 410 can be integrally formed with the mounting part 110 and / or the handle part 120 or assembled together after being formed separately. This utility model does not impose any limitations on this.

[0054] Furthermore, the handheld cleaning device also includes a control module 500 mounted on the base 100. The control module 500 is electrically connected to the battery pack 300 and the suction motor 400, respectively. The control module 500 is adapted to control the start and stop of the suction motor 400 and the adjustment of its speed. Specifically, the control module 500 can use a touchscreen control panel or a button control panel to realize the start, stop, and adjustment of the device. It should at least have buttons for controlling the start and stop of the suction motor 400 and buttons for adjusting the speed for user operation. This utility model is not limited to these specific features. In one embodiment, the control module 500 can be mounted on the mounting member 110, connected to the rear end of the mounting member 110, and adjacent to the end of the dust cup 200. Of course, in other embodiments, the control module 500 can also be mounted in other convenient locations on the base 100 for user operation.

[0055] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
